Dual Analog VU Meter 2-way Amplifier/Speaker Audio Switcher Box DB Panel Display (VU3)

This is a really cool product. Perfect for switching between channels feeling into the amp with no loss of sound quality. Love the look of it too.

Eventually figured out how to wire this up and it works well ,wasn’t happy having to convert rca to bare wires or replace with banana plugs ,description said flat 2025 batt needed for the control so ordered 2 and it’s aaa batterys 🤔.I think a guide to how to wire up would be very helpfull overall nice looking and works well .

This unit is exactly what I needed here. I have two amplifier/vintage receiver and two sets of speakers. The more modern setup has a Denon amp. with modern Yamaha speakers. The vintage Sansui has vintage speakers. I wanted to switch between the two utilising more modern speakers for the vintage gear and this device allows just that. There appears no degradation in sound quality going through the unit and is very easy to use and safe switching provides peace of mind use. A great product in my mind...a little fiddly getting all of the connections inserted, but straight forward to follow instructions provided. My top buy for a while!!

The unit itself looks really nice and well made, it's of a solid glossy black metal, quite weighty and it's dual VU-meter design is really aesthetically pleasing.Functionality-wise, the unit (almost) does what it's supposed to:- Effectively switches between 2 set of speakers or amps, without a noticeable degradation in sound quality- There is a dimming function for the VU meter LEDs and also 'Peak' LEDs can be turned on/off to indicate signal peaks. There is one bug however with the VU meter LED intensity, when turning down the brightness, there are 4 levels, probably corresponding to 75,50,25 and 0% whereas when turning it back up, there are only 3 levels, probably 33,66 and 100%. I would expect the same levels when going either way of the scale- Remote allows switching of Speaker and Amp inputs, controlling the VU meter LED intensity, as well as powering the unit On/Off.And therein lies the problem with the unit, namely, when turning off the unit, you can see the display LEDs going almost off (there is still a bit of noticeable light in the LEDs) and the VU meter needles deactivating, however, sound is still being passed on through the unit, to the speakers. I've also tried turning the unit 'Off' by long pressing the 'Amplifier' button on the unit itself, but behaviour is identical. So the only way to completely power off the unit is to unplug the USB-C cable powering it.This is far from ideal and defeats the purpose of the On/Off button on the remote pretty much.I've also tried the cheaper VU102 unit, which is not so fancy and can only have a single amp as input, but at least it completely powers off when pressing the on/off button.I've also ordered a second unit, thinking the first one is defective, however, second one had the same issue.I've tried contacting the manufacturer by their website contact form, to which to this day I didn't get a reply (2 weeks later), by Twitter, also no reply, and finally through WhatsApp, to which someone answered saying the technical team will be in touch, however, a week later, no one has replied.All this seriously makes me doubt the quality of their customer service, especially when buying from their web site directly and having to return a defective item let's say.One of the reviews for this unit on their website was also saying they received a defective unit, contacted them for a return, but didn't get any reply from the manufacturer.All in all, a really nice looking unit, a solid feel but let down by functionality bugs, of which, one is really disappointing.

This does a good job of both offering a couple of jumping dials and also acting as a splitter between two sets of speakers and two amplifiers. I am using mine with two amps, both vintage; a Sansui a607 MR and a Technics V6. I noted no alteration to the excellent sound quality I achieve. The dials dance very nicely and you can adjust the activity and also the light. At full on they are too bright, but you achieve a nicer compromise very easily. You can have a red 'peak' indicator light on or off, tho it doesn't actually measure 'peak' - it's all just to look good, same as the dials. The HUGE downer is the unit is way smaller than the pictures indicate. If a standard item of hifi gear is around 430mm this unit is around 2/5th of that. So it has to go on top of a stack if that's what you have, like me. Also, unless you use very thin and light weight speaker cables the unit racks back due to the weight. I use mid range, high quality cables and the rock back is immediate, even as I fit the first set. With all 8 sets I need quite a weighty door stop putting on top to hold the thing down. I will come up with a better solution at some point, I assume! But this is a real design fault and you do wonder if the makers even tested the thing in real world, typical hifi usage. So, I do like the functions it offers, just annoying trying to deal with the size and weigh problems.

works well

Great, does exactly what it says on the tin

The media could not be loaded. I perched this item connected it up as per instruction found one channel was not working no sound getting to Right hand speaker so I sent the item back! Thinking that sometimes products slip through pass checks I ordered another one this one worked I watched one film through my sistem lt was fin purchased another Dolby serround film got to 50 minutes and the left channel stopped working and that was the end of a second until my tack is their is bad components in this product it looks nice but won’t last
